To all the
Women I know – which Metal you like most – the most precious one or the one
with highest utility ! – incidentally, can you make anything from this photo !
(of course of a metal that you buy so often and use daily !!)
பெண்மணிகளே
! நீங்கள் தினமும் அறுசுவை (!) சமையல் செய்பவர்களா !! - தங்க நகைகள்
அல்லது தங்க பிஸ்கட்கள் வாங்குவது உங்கள் மன விருப்பமா ? உங்களிடம் எவ்வளவு கிலோ வெள்ளி
உள்ளது !! - இவற்றை தவிர உங்களுக்கு எந்த உலோகம்
அதிகம் பிடிக்கும் !
Human’s
lust for the yellow metal Gold knows no boundaries. It is more than a precious metal ! It represents
wealth, security, tradition, prestige, sentiment and, sometimes, an
irresistible obsession. 24-carat gold is
essentially pure gold (approximately 99.9%). It is too soft for most everyday
jewellery; so other metals are added to increase hardness, strength and
durability, and sometimes to alter colour. The resulting alloy is then used to
manufacture jewellery. The higher the
percentage of other metals added in the carat of gold , the purity of the gold itself low.
Internationally, Gold
has fallen below the psychologically important US$4,000 level and reached a
one-year low on October 30, according to Reuters. On November 4, gold gained
approximately 3.4%, its biggest daily rise since August 19. On November 5, it
reached US$4,146.63 per ounce. A weaker US dollar and falling US Treasury
yields helped this recovery.
Back home, as of
Friday, 6 November 2026, gold is trading at exceptionally high levels. At Chennai the indicative rate of 24K gold is
- ₹14,603/g - ₹1,16,824
8 grams
All that
glitters is not gold and life is not only about the yellow metal. There is
another cousin equally shining. The one
with the chemical symbol ‘Ag’ – soft, white, lustrous transition metal, having
the highest electrical conductivity and one in pristine pure form considered
auspicious - the Silver.
Silver has been valued as a precious metal for long and is also used to
make ornaments, jewellery, high value utensils [silverware] and considered
prestigious. Born with a silver spoon is
a common idiom and eating in a silver plate is considered exhibiting one’s
richness.
If you
have already found it – it is about Eversilver !! the familiar South
Indian, term for stainless steel. The
name probably comes from its enduring silvery shine. Unlike ordinary silver,
stainless steel does not tarnish easily, requires relatively little maintenance
and is durable. It is an interesting example of Indian English evolving
through local usage. In Tamil Nadu, we have even made it a noun for an entire
category of household goods!
Stainless steel is a
type of steel that resists rusting and corrosion. It is an alloy – meaning it
is made by combining iron with other elements, principally chromium. The main ingredients are: Iron, Chromium, Nickel, Carbon and other
elements present in varying proportions.
When chromium is present in steel, it reacts
with oxygen in the atmosphere to form an extremely thin, invisible protective
layer called chromium oxide. The 316 stainless steel is particularly useful in marine
environments because its molybdenum content improves resistance to chloride
corrosion.
In short,
what we casually call eversilver is actually an intelligently engineered iron
alloy whose surface chemistry protects it from rust! The
story of stainless steel is quite fascinating. What we now casually call
eversilver in South Indian households was actually developed through
experiments in metallurgy in the early twentieth century. Its adoption for
kitchen utensils came later, when manufacturers recognised that it was an
almost ideal material for everyday cooking and dining.
An inventor of
eversilver - is a very ambiguous term. Is this the first person to think, to
document, to patent, or to produce? Again, stainless steel wasn’t truly defined
until 1911, so are we to cast aside those chromium-iron alloys that don’t quite
meet the minimum requirement of 10.5% chromium? It seems like anyone and
everyone has a different claim to being labelled the ‘inventor’ of stainless
steel; from Britain, Germany, France, Poland, the U.S.A., and even Sweden.
The cogs were set in
motion by Englishmen Stoddart and Faraday circa 1820 and Frenchman Pierre
Berthier in 1821. These scientists, among others, noted that iron-chromium
alloys were more resistant to attack by certain acids, but tests were only
carried out on low chromium content alloys. Attempts to produce higher chromium
alloys failed primarily because of scientists not understanding the importance
of low carbon content. By 1913, Harry Brearley,
a British metallurgist from Sheffield, England created a steel with 12.8% chromium and 0.24%
carbon, argued to be the first ever stainless steel. The circumstances in which
Brearley discovered stainless steel are covered in myth; some enchanted tales
of Brearley recite him tossing his steel into the rubbish, only to notice later
that the steel hadn’t rusted to the extent of its counterparts, much like
Alexander Fleming’s experience 15 years later.
Other more plausible,
(but less attractive), accounts claim it was necessary for Brearley to etch his
steels with nitric acid and examine them under a microscope in order to analyse
their potential resistance to chemical attack. Brearley found that his new
steel resisted these chemical attacks and proceeded to test the sample with
other agents, including lemon juice and vinegar. Brearley was astounded to find
that his alloys were still highly resistant, and immediately recognised the
potential for his steel within the cutlery industry.
His original
assignment was not to develop kitchen utensils! He was investigating better steel for gun barrels. Gun barrels
suffered from erosion and corrosion due to heat and chemical action. He
experimented by adding chromium to steel and discovered that a particular chromium-rich
steel resisted rusting remarkably well. His invention was initially called
rustless steel. The term stainless steel subsequently became popular.
He realised that his
new steel had an unexpected advantage: it resisted not only rust but also
staining from acidic substances such as vinegar and lemon juice. . .. .. now we keep hot Sambar, lime Rasam,
buttermilk, water and everything in Eversilver utensils and buy them whenever
we visit a shop / super market or bulk sales place like Sowcarpet area.
Happy buying – keep the
craze for metals burning always !!
